I have owned other NAD products over the years and found them to be outstanding. I replaced a 10 year old NAD T761 with the T748. I have a projector system with 5.1 Surround Sound and found it easy to hook up with the HDMI input.
Great sound; Easy to hook up; Auto Calibration using the mike is a real plus
Owner's Manual could provide better examples relative to setting up the Listening Modes
